For each fuel rod in a reactor assembly, only 5 percent of its energy is consumed before fission can no longer be sustained efficiently for power production and the fuel assembly must be replaced. Power plants currently store the used fuel on-site. Information on the composition of the used fuel is essential for the design of safe storage, transportation and final repository facilities and for inspection and verification to safeguard nuclear materials. Improved accuracy in prediction of the spent fuel isotopic composition leads to increased efficiency in the facility designs and higher confidence in the safeguard protocols. http://phys.org/news/2016-03-benchmark-validates-global-nuclear-reactor.html

But the greatest damage to the complex, and the greatest release of radiation, may have been caused by explosions of hydrogen gas that built up inside some of the reactors.http://phys.org/news/2013-07-nuclear-fuel-rod-cladding-safer-power.html

Business Thu, 17 Mar 2011 19:05:03 ESTnews219607486How does a nuclear meltdown work? (w/ Video)(PhysOrg.com) -- When working properly, nuclear reactors produce large amounts of heat via nuclear fission reactions. The heat converts the surrounding water into steam, which turns turbines and generates electricity. But if you remove the water, you also remove the most important cooling element in a nuclear reactor and open up the possibility for nuclear meltdown.http://phys.org/news/2011-03-nuclear-meltdown-video.html
